What happō kanamono means
Happō kanamono are band-shaped decorative metal fittings nailed across the doors of gates, storehouses and shrine buildings. They both hold the door planks together and ornament the doors. The ends of the bands are often cut into arrow-feather, flower or scroll shapes or pierced with openwork.
Being nailed across the joints between planks, they are also said to help prevent warping and splitting. Large gates may have rows of them at top and bottom, combined with other fittings such as nipple-shaped bosses and hinge straps for a heavy, splendid door.
Reading the records
Records mention them among decorative fittings. The east gate of the Saito family house in Sabae, Fukui, a braced udekimon built to receive honoured guests at the reception wing, is made mainly of zelkova, its doors elegantly decorated with many fittings including happō kanamono. The earthen wall of the Iwase family house in Sakaide, Kagawa, carries a happō-like motif at the centre of the gable of its corner, borrowing the shape of the fitting for plasterwork.
On site, look for metal bands running across a door and the shape of their ends.
